Amazon has added to its portfolio of carbon-free power purchases with a deal to purchase 1.9 gigawatts by 2042 from Talen Power’s nuclear plant in Susquehanna, Pennsylvania. The purpose: to energise new and present knowledge facilities within the area.
The ability buy settlement introduced on June 11 builds on an present relationship, and it helps Amazon’s plan to take a position $20 billion on Amazon Net Providers amenities in Pennsylvania. The Talen association hints at one other growth, utilizing small modular reactors, constructing on investments Amazon disclosed final October. Phrases weren’t disclosed.
Amazon’s new contract is the third high-profile nuclear deal introduced since early Could, alongside ones by Google and Meta. Microsoft can be searching for methods to go nuclear: Its largest transfer up to now was an settlement final fall that may reopen a shuttered reactor at Three Mile Island.
All 4 firms view nuclear power baseloads as an vital addition to their carbon-free power portfolios alongside photo voltaic, wind and geothermal.
“There’s this actually untapped useful resource of nuclear power that’s present or that has exited the grid lately as a result of the economics have pushed them off as extra renewables come on-line,” Bobby Hollis, vice chairman of power at Microsoft, instructed Trellis final September. Microsoft’s first publicly introduced nuclear deal was in Could 2023, with fusion firm Helion Power.
Favorable circumstances
The political local weather is conducive to retaining present vegetation on-line or restarting retired ones: President Trump has signed govt orders propping up nuclear, together with ones to encourage superior applied sciences and broaden U.S. nuclear capability to 400 gigawatts by 2050, in contrast with 100 gigawatts at present. He even supported the restart of a reactor in Michigan, which obtained a $1.5 billion rescue mortgage from President Biden.
Nuclear power might meet as much as 10 % of knowledge middle electrical energy demand by 2035, in line with an April 2025 Deloitte evaluation. A single reactor utilizing legacy applied sciences generates about 800 megawatts; AI knowledge facilities can require as much as 5 gigawatts.
Curiosity has additionally sparked a surge in demand for small modular reactors, which provide about one-third the producing capability of bigger models. The worldwide pipeline of initiatives was 47 gigawatts on the finish of the primary quarter, with greater than half of the capability within the U.S., in line with projections by analysis agency Wooden Mackenzie.
“The surge in knowledge middle demand has propelled nuclear small modular reactors to a significant participant sooner or later power combine,” stated David Brown, director of power transition analysis at Wooden Mackenzie. “[They] stay a high precedence for the Trump administration and with coverage tailwinds, improvement ought to speed up and broaden to be a major supply of fresh power.”
There’s nonetheless loads of uncertainty over whether or not the initiatives will really be constructed: It should take $300 billion to construct the present pipeline of small modular reactors.
“Nuclear has had many false begins,” stated David Wilson, CEO of Power Exemplar, which develops power modeling software program. New builds will take years to come back on-line, he famous. “I’m optimistic for the know-how, however I’m very pragmatic,” he stated.
Energy producers to look at
Effectively-established utilities and little-known builders are on the middle of the nuclear offers introduced by Amazon, Google, Meta and Microsoft over the previous 18 months. Listed below are ones making headlines:
Constellation Power
The Baltimore-based producer, which operates the most important U.S. nuclear fleet with 21 reactors, is Microsoft’s companion for the Three Mile Island restart. It’s additionally the provider for Meta’s 20-year-long energy buy settlement, introduced June 3, to purchase 1.1 gigawatts of nuclear power from the Clinton Clear Power Heart in Illinois.
Meta’s dedication will assist an growth of the power’s output and ship $13.5 million in annual tax income, in line with the announcement. The location had been slated for retirement.
Dominion Power
The Virginia utility operates seven nuclear vegetation in Connecticut, Virginia and South Carolina. It obtained approval to increase the working licenses in Virginia — an information middle hotbed — for twenty years and is conducting feasibility research on small modular reactors that would add 300 megawatts of energy within the state.
Elementl Energy
This stealthy nuclear improvement firm, situated in Greer, South Carolina, and based in 2022, has been contracted by Google to organize a minimum of three websites (places undisclosed) for superior nuclear installations. Every set up would have a technology capability of a minimum of 600 gigawatts, and Google would have the choice to purchase that energy, below the settlement disclosed Could 7.
Elementl’s mission is to deliver 10 gigawatts of superior nuclear on-line within the U.S. by 2035. It has gained favor with the Division of Power, by the company’s Gateway for Accelerated Innovation in Nuclear program. Elementl is backed by infrastructure funding agency Breakwater North and Power Affect Companions, the funding agency created by a who’s-who within the power business.
Power Northwest
Amazon’s investments in small modular reactors embody an October 2024 settlement with this group of utilities, situated predominantly in Washington state, which have dedicated to assemble small modular reactors. The Amazon contract will assist 4 initiatives, with a mixed technology capability of 320 megawatts within the first part and an choice to scale as much as 960 megawatts.
Kairos Energy
Google’s first nuclear partnership, introduced in October 2024, was with this developer of small modular reactors primarily based in Alameda, California. The plan is to construct installations in areas the place they will provide electrical energy to Google knowledge facilities, by way of company energy buy agreements.
The overall pipeline referred to as for below the deal is 500 megawatts — which interprets right into a half-dozen reactors — with the primary website to be constructed by 2030. Monetary phrases weren’t disclosed. Kairos can be working carefully with Elementl, Google’s different nuclear ally.
Oklo
Knowledge middle developer Change, which counts huge firms together with eBay and FedEx amongst its prospects, signed a contract to purchase 12 gigawatts of electrical energy from nuclear initiatives being constructed by this Santa Clara, California, nuclear firm.
Oklo is run by a administration workforce that features alumni from Apple, Google and Tesla. Its fission know-how can use nuclear waste as gas, and the corporate on June 11 introduced a U.S. Air Power contract to construct a reactor in Alaska.
Talen Power
Based mostly in Houston, Talen is almost all proprietor of the Susquehanna nuclear plant in Pennsylvania. Amazon moved to purchase an information middle campus powered by the location in March 2024. The grid interconnection allow wanted to assist that deal was twice rejected by the Federal Power Regulatory Fee.
The expanded relationship will maintain Susquehanna’s energy on the PJM grid. It provides PPL Electrical Utilities as transmission and supply companion. “Connecting giant load prospects like knowledge facilities to our transmission system helps decrease the transmission parts of power payments for all prospects, as giant load prospects pay important transmission fees on our community,” stated PPL President Christine Martin.
Talen and Amazon are additionally planning small modular reactors in Pennsylvania.
